Problems solved by technology

In this case, the propeller only plays the role of propulsion, and the material will not disperse if it is not tossed and stirred by external force, and the uniformity of extraction is poor, which greatly limits the improvement of extraction rate and is not conducive to the improvement of equipment performance. play, reducing the cost performance of the equipment
To meet the requirement of high extraction rate, it is necessary to increase the length of the extraction tube, which increases the floor space and investment of the equipment; the second is that when the extraction tube is circular, when the total volume of the material in the extraction tube exceeds the extraction tube When the effective total volume is 40%, the material will rotate with the rotation to cause the material to rotate in situ. Because it is a continuous belt blade, the material will be tightly piled up on the side of the extraction tube, forming a shaft-holding effect, which will cause blockage, which also greatly limits Improve the performance of the extraction tube and reduce the cost performance of the equipment

Embodiment 1

[0020] Embodiment 1: as Figure 1-2 Shown, a kind of countercurrent extracting device, it comprises extraction tube 9, is provided with propeller 14 in extraction tube 9, and propeller 14 is made of shaft 24 and vane 25, and described vane 25 is sheet shape, and described vane 25 is on shaft The surfaces of 24 are arranged side by side and at intervals along the axial direction, such as Figure 6-9 and 14-16, the blades 25 are all located on one side of the shaft 24 in a row or as Figure 10-13 As shown in 17-19, the blades 25 are distributed on the upper part and the lower part of the shaft 24 and arranged in two rows, and the blades on the upper part and the blades on the lower part are alternately arranged.

[0021] Such as Figure 6 , 7, 10, and 11 show that the blade 25 has a wide blade end and a narrow blade root, and the blade root is directly connected to the shaft 24, and the centerline of the blade 25 is perpendicular to the shaft 24 centerline.

[0022] Such as ...

Embodiment 2

[0025] Embodiment 2: The similarities between this embodiment and Embodiment 1 will not be repeated, and the difference is that image 3 As shown, the blades of the propeller 14 between the baffle plate 17 and the feed inlet 8 can be continuous belt blades 22 .

Abstract

A countercurrent extraction device, which includes an extraction tube, and a propeller is arranged in the extraction tube. The propeller is composed of a shaft and blades. All of them are located on one side of the shaft and arranged in one row, or the blades are distributed on the upper part and the lower part of the shaft and arranged in two rows, and the upper blades and the lower blades are alternately arranged. Because the blade is sheet-shaped to propel the material, it will also tumbling and scattered to play a stirring role; the material will tumbling from one side to the other side with the rotation of the propeller, although part of the material will rotate with the blade in situ, the material It will not accumulate to one side at the same time, so it will not form a continuous close accumulation, and it will not form an axis-holding effect, so that it will not form a blockage in the extraction tube. After many tests, it has been proved that even if the total volume of the material is greater than 80% of the total volume of the extraction tube, there will be no clogging, so that the efficiency of the extraction tube can be maximized and the cost performance can be significantly improved.

Description

technical field [0001] This program involves a device that uses liquid medium to extract solid materials (hereinafter referred to as materials), especially the material and liquid medium flow in the opposite direction in the extraction tube, and a spiral arrangement of sheet-shaped blades is built in the extraction tube. The thruster propels the countercurrent extraction device for material delivery. Background technique [0002] In the prior art, the technical solution closest to this application is the continuous countercurrent extraction machine in use. This continuous countercurrent extraction machine is composed of an extraction tube, and the inside of the extraction tube is equipped with a screw propeller. The screw propeller is a continuous belt. Type blades are arranged in a spiral shape along the axial direction. Under the action of the screw propeller, the material is transported from one end of the extraction pipe to the other end, and the extraction solvent flows...
